PAINT on vaRiHsH nEMovEn.

Be it known that -I, CARLEroN ELLIS a citizen of the United States, and resident of White Plains, in the county of Westchester and State of New York, have made certain new and useful Improvements Relating to Paint or Varnish Removers, of which the following is a specification.

This invention relates to paint or varnish removers and-relates especially to removers comprising solvents of the acetal order.

Many oxidation products and alcoholic bodies of the acetal order are desirable solvents for use in finish removers. Acetal, which may be derived by treating ethyl alcohol with an oxidizing agent such as manganese dioxid and sulfuric acid is a pleasant smelling li uid boiling when pure .at about 104 C. an having a specific gravity of .83. The methylacetal may be derived from methyl alcohol and the regulated oxidation of denatured alcohol produces mixed acetal products, such as methyl ethyl acetal, and so orth. A number of other compounds of the acetal order are desirable, including the oxy acetals, chlor acetals and other acetal derivatives. Such solvent material of a generally acetal character may be used in removers in connection with. other loosening finish solvent material, that is solvent material having a generally alcoholic character or action in removers, such as methyl, ethyl, propyl, butyl, amyl, 'allyl, and other strict alcohols, preferably in their commercial forms, including denatured alcohol, acetone alcohols and other ketonic bodies such as methyl ethyl ketone, ethyl butyl-ketone, oil of acetone, acetone and its condensation 'derivatives. Suitable penetrating finish solvent material, that is, solvent material having a generally benzolic character or action in removers may also be employed, such as benzol and its homologues and their commercial forms and also the somewhat analogous petroleum hydrocarbons such as benzin, as well as ethers, carbon-bisulfid, turpentine,

. wood turpentine, carbon-tetrachlorid, chlorbenzol,chlorhydr1ns and other chlorinated solvents.

Although not necessar in all cases, it is usually desirable to emp oy in the removers suitable stiflening material such as wood I flour, starch, cork dust, Peruvian bark, refuse, ground peat, magnesia, whiting, infusori'al' e'arth, casein and other proteid material in the form of emulsions, if desired, and soapylor waxy bodies, such as casein, parafiin, bayberry tallow, Japan wax,'sc'a rnauba, Chinese wax, beeswax, etc., as well.

in the more energetic solvents therefor,

although this is not always necessary. -An illustrative remover of this character may comprise acetal 10 gallons, bezol 10 gallons, acetone 10 gallons, 7 pounds ceresin wax and 15 pounds cork dust. Another remover may comprise methyl ethyl acetal 5 gallons, acetal-10 gallons, ceresin wax 5 pounds, to which 10 gallons of benzol may be added, when aremover especially ada ted for copal finish is desired. Another illustrative re- 'mover may comprise acetal 10 gallons and pyroxlin 10 pounds, to which may be added 4 gallons of benzol, toluol or perolic ether, 10 gallons of methyl ethyl ketone and 5 pounds of wax, such as ceresin, for use with paints and other finishes. Another illustrative remover may comprise acetal 60 gallons, defiiatured alcohol 10 gallons and ceresin or 0 her waxy material 30 pounds.

This invention has been described in con-.

nection with a number of illustrative ingredients, formulas, proportions and processes, to the details of which disclosure the invention is not, of course, to be limited.

What is claimed is 1. The finish remover comprising approximatel benzol 10 gallons, 7

' pounds of cork dust.

2. The finish remover comprising approxipounds ceresin and 15 acetal10 gallons, acetone 10 gallons,

matelyacetal 10 gallons, acetone 10 gallons, benzol- 10 gallons and stifl'ening *materialcomprising wax.

3. The finish remover comprising finish solvent material of the acetal order, loosening finish solvent material, aromatic penetrating'finish solvent material and incorpotrating finish solvent material 10 gallons, and dissolved film-forming evaporation-retarding stiffening material.

5. The finish remover comprising approximately finish solvent material of the acetal order 10 gallons, acetone 10 gallons, penetrating so vent material and incorporated stiffening material including mineral Wax.

6. The finish remover comprising approximately acetal 10 gallons, acetone 10 gallons, aromatic penetrating finish solvent material 10 gallons and incorporated stiifening material including dissolved Wax.

7. The substantially fluent finish remover comprising composite volatile finish solvent material includlng a solvent of the acetal order and incorporated evaporation-retarding stiffening material including dissolved wax.

8. The substantially fluent finish remover comprising composite volatile finish solvent material including acetal and incorporated stiffening material including dissolved mineral wax.

9. The substantially fluent finish remover comprising composite volatile organic finish solvent material including a solvent of the acetal order and incorporated stifiening material including dissolved mineral Wax.
